In this paper, we deal with a new techno-economic modeling and analysis for optical access networks. In deploying the fiber-to-the-home (FTTH) architecture, network planner needs to consider the following techno-economic issues: when do we need to upgrade existing local access network to FTTH network? how much do we invest to maximize profit? In order to answer these techno-economic questions, we need to consider the impact of emerging technologies and business environment. Toward this end, we develop a new techno-economic modeling to deal with the inherent complexity of technology evolution and cost economics. In particular, the new modeling approach provides us with an techno-economic analysis of technology alternatives such as ethernet passive optical network (E-PON) and wavelength division multiplex passive optical network (WDM-PON). In this analysis, we focus on the impact of critical factors such as the cost characteristic of proposed architecture and digital subscriber line (DSL) subscriber's churn-in to FTTH service and churn-out. We develop mixed integer-programming models for finding the evolution path of local access networks to broadband network architectures.

Purpose: This study was done to identify risk factors influencing high school students to runaway from home. A comprehensive analysis of individual, family and social environment-related factors was done. Method: The participants in this descriptive survey on causal relations were 974 students enrolled in high school who were selected by convenience sampling. The data collected in June and July, 2003 were put in to logistic regression analysis to build a prediction model. Results: 1) Individual-related factors for running away in high school students were experience with smoking and sexual intercourse. 2) Family-related factors for running away in high school students were economic status and physically ill-treatment of the types of ill-treatment. 3) social environment-related factors for running away in high school students were number of delinquent friends. Conclusions and Recommendations: Running away from home among Korean high school students was associated not only with individual factors, but also with family and social environmental factors. The findings of study suggest that board intervention programs should be provided to prevent running away form home by adolescent. It is also recommended that a program be developed that can help control the variables identified in this study along with follow up study to verify the model.

This study makes suggestions on the contents of home economics to form adolescents' values of a healthy marriage and family. For this objective, family-related contents of high school home economics textbooks between Korea and the U.S. were comparatively analyzed using a qualitative interpretation method, based on the elements of a healthy family. Obtaining nine types of high school technology & home economics textbooks (2009 revised curriculum), two types of high school home economics science textbooks (2009 revised curriculum), and five types of the U.S. home economics textbooks for grade 10 to 12, contents elements, described contents, pictures, illustration, and activity tasks of the contents were examined. This study discussed the implications of family-related content in home economics high school textbooks of Korea as well as presented suggestions to be used as basic data for the development of subject content. The results of the study can be summarized as follows. In the results of analyzing the family-related contents in home economics textbooks of both countries, Korean home economics textbooks emphasized the contents meeting a democratic and gender-equal family relationship, maintenance & creation of healthy family life culture, rational resource management, and support for children's growth & development. However, U.S. home economics textbooks focused on elements such as economic stability of family, stable food, clothing, and shelter, open conversation, support of children's growth & development, rational resource management, sharing family roles, healthy citizenship, and harmony between work and family.

The purpose of this study is to examine the regional differences of 0-12 aged children's environment based on their parents' socioeconomic class and on the character of the settlement. One thousand and two hundred households were investigated and the results are as follows. It is revealed that families in low socio-economic class are more likely to be exposed to noise and home crowdedness. Families living in spontaneous settlement are deprived of natural light and the roads to their homes are steep and narrow. Low income families face a housing affordability crisis. Most of them pay housing rent on monthly basis. The basic infrastructure of low income neighborhood is lacking convenient facilities like shopping centers, public transportation systems, banks, public parks, and libraries. This lack of facilities is more severe in spontaneous settlement. Instead, bars and taverns are located in their neighborhood. Accessibility to parks and resource centers is an important factor that makes both middle and low income families consider their neighborhood to be positive and this condition is counted better in social housing area than in spontaneous settlement. On the contrary, social networks like friends and relatives are strong in spontaneous settlement and families in poverty value these relationships. Such networks are weak in social housing area and this difference is not related to their residential period. Low income families living in social housing area are more pessimistic about their future and this view might result from their counterpart middle class neighbors and the weak social networks.

개발도상국에서 선진국으로의 국제결혼의 가장 중요한 동기로는 경제적으로 보다 여유로운 삶의 추구를 들 수 있다. 그러나 이들 결혼이주자들의 결혼 전후의 경제적 상황을 비교분석한 경험적 연구는 전무하다고해도 과언이 아니다. 본 연구는 한국의 베트남 여성 결혼이주자를 사례로 결혼 전후의 경제상황의 변화에 대한 인식을 그들의 사회 경제적 특성과 관련하여 분석하였다. 한국의 베트남 여성 결혼이주자의 결혼동기 역시 경제적인 이유인 경우가 약 80%정도를 차지하였다. 그러나 실제로 이들 가구의 경제적 수준은 상대적으로 매우 낮다. 이를 반영하듯 이들의 절반 정도는 결혼 전후 경제적 상황이 큰 차이가 없는 것으로 인식하고 있으며, 결혼 후 경제적 상황이 나아졌다고 인식하는 비율이 그렇지 않다는 비율보다는 4배 이상 높았다. 이러한 결혼 전후의 경제상황의 변화에 대한 인식과 그들의 사회 경제적 특성과의 관계에서는 본인과 남편의 교육수준, 한국어 능력, 직장 유무, 남편의 소득 수준 그리고 가계관리 여부, 한국에서의 거주기간과는 정(正)의 상관관계가 있었다. 그러나 베트남에서의 직업 유무 및 베트남으로의 송금 여부와는 상관관계가 별로 크지 않는 것으로 나타났다. 또한 베트남 여성 결혼이주자의 대부분은 현재 본인의 가족뿐만 아니라 베트남 가족의 경제적 여건을 제고하기 위한 취업에 대한 의욕이 매우 높았다. 따라서 이들의 취업을 위한 보다 구체적인 정책적 대안이 마련되어야 할 것이다.

This longitudinal quasi-experimental research was conducted to develop parent role education program and to evaluate the effect of this program for mother-infant interaction, childrearing environment and infant development. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their healthy mothers. The sample consisted of eighteen mother-infant dyads for intervention group and sixteen dyads for control group. Data were collected from March 15th in 1999 to Jun 20th in 2000. The intervention group received programmed education consisted of discharge education, telephone counselling, and home visiting care. But control group were collected data without programmed education. In this study, the Nursing Child Assessment Teaching Scale(NCATS) devised by Barnard was used to determine the mother-infant interaction, HOME was used to determine the childrearing environment, and Griffiths mental development scale was used to determine the infant development. The data were analyzed using SPSS Win using chi-square test, t-test, and repeated measure ANOVA. This study was focused on the results of twelve months time point. Summaries of the results were as follows: 1. There was no significant difference in mother-infant interaction(NCATS) between intervention group and control group. But both of two groups showed significantly higher in interaction score at twelve months than at six months in the subscales of social-emotional growth fostering, and responsiveness to caregiver. 2. There was no significant difference in childrearing environment(HOME) between two groups at twelve months. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of maternal involvement with child(p=.001), and maternal emotional-verbal responsivity(p=.048). 3. There was no significant difference in GQ of the Griffiths mental development scale between two groups, although significant difference was found in performance subscale. 4. Infant development at twelve months showed significant correlation with mother-infant interaction and childrearing environment at six months, although mother-infant interaction and childrearing environment at twelve months did not show significant correlations with infant development at twelve months. 5. Developmental scores at six months showed significant correlations with variety in daily stimulation, and mother's emotional, verbal responsivity, whereas developmental scores at twelve months showed significant correlations with acceptance of child behavior at six months, and appropriate play material at twelve months. In conclusion, the maternal education program for primipara showed long term effect in some categories in organizing the childrearing environment, and fostering the infant development. We suggest further study and implications of parent role education program for high risk parents such as parents in low economic status or with premature babies.

Purpose: This study aimed to find grounds for the development of a health promotion program by examining the risk factors affecting children in low-income families. Methods: This was a cross-sectional study. The subjects were 288 children under 13 years of age in We-Start, W city. The tools used included a household information questionnaire and risk assessment tools. The data were analyzed using t-test, ANOVA, and multiple regressions. Results: Risk factors like disability problems (β=.38, p<.001), residential environment (β=.37, p<.001), parenting type (β=.27, p=.003), the foster's educational level (β=.22, p=.011), and the gender of the child (β=.19, p=.030) explained 51% (p<.001) of the preschoolers in crisis. For the schooler, academic achievement (β=.39, p<.001), disability problems (β=.24, p<.001), adaptation to school (β=.23, p<.001), noise from the environment (β=.20, p<.001), and the foster's job (β=-.15, p=.007) explained 50% (p<.001) of crisis of schooler. Conclusion: The study found that children (disability, gender), family (residential environment, type of parenting), and caregivers (educational level, economic competence) had a complex impact on crisis situations. In children of a school-going age, school life appeared to be an important influencing factor. Therefore, an integrated case management approach that considers children, carers, and the home environment is necessary.

The considerable increase of the elderly with dementia is expected annually and when we think about the family members' and the patients' suffering, it could be painful. Above all things, it imposes heavy economic burdens on the family members that have patients who suffer from diseases of age like dementia or paralysis that caring them at home and also, it is not desirable for those old people in point of physical or environmental circumstances for medical care. Thus, it is needed urgently that the expansion of specified facilities and improvement of services for these old people. Under this present condition, it is the special feature that the subject of research is people/facilities that offer services, not the elderly with dementia-the main user of those facilities. This proposal aims to make a study of expansion and improvement the old people's welfare facilities by using remodeled closed Small and Midium Hospitals which are the bad effect of economic growth. Also, it can save money with re-using abolished buildings which is property of the nation and protect environment too. In this study, We examine the present conditions of old people's welfare institution, and research a factor of remodeling for welfare facilities. Then we will verify remodeling-possibility which is concrete and working by using the product of this study.
